Answer 1

[AI-generated answer — Bot GPT 3.5]

Let x be the number of toy cars that Jim has.

According to the ratio, Alex has 8x toy cars.

We are also given that Alex has 40 more cars than Jim, so:

8x = x + 40

7x = 40

x = 40/7
x = 5.714

Since x must be a whole number, we round down to the nearest whole number (Jim cannot have a fraction of a car), so Jim has 5 toy cars.

Therefore, Alex has 8*5 = 40 toy cars.

In total, they have 5 + 40 = 45 toy cars.
